Valve noise

[Pressureangle]

I knew that header would suck you in like an oil thread.

My '89 Mille GT is my third big block. I've done little with it since I bought it save install Mistral mufflers, replace the busted up instrument cluster, and give it a basic tune up; timing, valve adjust, carb balance. It seems to run quite well. But it has a lot more noise at idle than the others. It's quiet as soon as you get a few revs in it. Seems worse on the right side. 

Timing chain adjuster? It's showing just under 37k miles, and looks about right for that age and mileage. 

The previous owner quite obviously had no clue, as the carbs were wacked and the clutch was so tight it slipped above half throttle. Hopefully it won't need a new one, but I have to put some miles on it to know.

Of course, I'll not be able to stay out of it but there's plenty stacked in front of it, and the forum's been pretty quiet so I'm volleying the shuttlecock.
